What is an O2 upgrade deal?

Already a happy O2 customer but want a new phone or a different tariff? Then upgrading is an option for you. Keep all of the existing benefits, like discounts and concert tickets with O2 priority, and free wi-fi on the move with O2 Wi-Fi, but get yourself a brand, spanking new handset and a tariff that suits your phone usage better.

Alternatively if you are on a different network but your contract is coming to an end, and the O2 perks are catching your eye you can 'upgrade' your phone/deals by signing up as a new customer and porting your existing number over to O2.

Can I get a better deal by upgrading with my current network or by changing providers?

Even if you are very happy with your existing network provider, it is worth having a browse of what is currently on offer both on your current network and from other providers. There are often great deals and discounts to be found if you compare deals.

The best offers often go to new customers, and as you can port your existing mobile phone number over to a new phone/SIM (a.k.a. take your existing number with you) you may have nothing to lose by moving networks.

If you can't bear to leave your current provider then use our upgrade deals table for your provider to find and compare the best upgrade deals currently on the market. Choose from the drop down filter options to find the perfect upgrade deal for you.

Can I get an early upgrade on O2?

If you are an O2 Refresh customer, you can change phones whenever you want because on O2 refresh your bill is split into two parts: an Airtime Plan and a Phone plan.

The Airtime Plan is the part that covers all of your calls, texts and data, and the Phone Plan is the cost of the phone. So, if you want to upgrade to the latest phone on the market, you just need to pay off the Phone Plan, before you can upgrade, taking the remainder of your Airtime Plan with you.

Great for anyone who loves to have the very latest smartphone on the market.

If you are on a standard O2 contract you might still be able to upgrade early but you will have to pay a fee unless your contract is due to end in under 30 days.

Can I upgrade via mobilephonechecker?

Yep, even if you didn't sign up to your existing contract through us you can upgrade via this site.

Find an o2 sim only deal

If you are still happy with your phone but are reaching the end of your contract and want a better deal then it is worth taking a look at SIM only deals. A SIM only deal, unsurprisingly, gets you a SIM but not a new phone. There are various SIM only options available from each network from fully unlimited minutes, texts and data for a set monthly amount; to pay as you go SIMs where you only pay for what you use.

If you want to stay flexible, a 30 day SIM contract - also known as a rolling contract - may be the best option for you.

Do I have to stay with my current network to upgrade?

You can also get a great new phone and deal by moving to a different network. Although this isn't the conventional meaning to the term 'upgrading', as you aren't sticking with the same provider, by porting your phone number across to the new network you can keep your contact details and still get a better phone and tariff.

The site aims to enable you to easily compare the vast majority of tariffs available in the marketplace.However, we do not include every package (e.g. legacy tariffs no longer available, tariffs only available to existing/specific customers), nor do we detail every aspect of every tariff e.g. international out of bundle rates, on-network minutes, etc.

For those tariffs which offer "unlimited" allowances, there may be times where traffic management or fair usage policies apply.There may also be additional charges for those that require payment methods other than direct debit and for itemised/paper billing.
